The formation and investigation of Fe3Si thin films by pulsed laser deposition is reported. The structural properties depending on the formation parameters are investigated. Three different approaches to the synthesis of iron-silicide thin films by p

A new type of binary and pseudobinary invar materials based on intermediate valence samarium compounds Sm0.8B6, Sm1 – xLaxB6 (x = 0, 0.1, 0.22, and 0.5), Sm0.67Y0.33S, Sm0.55Y0.45S, and Sm2.75C60 are developed. The Weiss two-level invar model is us

This work focuses on multilayer monochromatization systems (MMS) designed for X-ray spectroscopy stations of synchrotron radiation (SR) user-oriented centers for operation in a wide range of energy resolutions and at a high temporal resolution of the

We investigate the lattice dynamics of frame-cluster dodecaborides ZrB12 and LuB12 in the framework of the electron density functional theory. Our ab initio calculations are performed using the Quantum Espresso package, with PAW-type pseudopotentials

This study is the first attempt to apply the two-level Weiss model for the invar alloy to intermediate-valence samarium systems. This model is instrumental in giving a quantitative characterisation of the anomalous magnetic contribution to the coeffi

Two new operation modes, “pink beam” excitation, which has the energy bandwidth defined by X-ray mirrors and filters, and “broadband beam”, where the energy bandwidth is defined by the reflection from a multilayer monochromator, were implemen

In this paper lattice dynamics of dodecaborides RB 12 (R = Zr, Yb, Lu) is studied using the superatom model. Within this model, a group of strongly bound boron atoms placed at the vertices of cubooctahedron is substituted with a superatom, which poss

The work is focused on the thermal expansion of composites based on valence-unstable systems. The main motivation was to create invar-like materials of a new type and to develop approaches to the quantitative description of coefficients of thermal ex
